Guest Speakers in the Middle School Classroom | Posted in Next Generation Science Standards

Aloha! I teach 7th grade life science from 8:40a-2:20p and have about 8 guest speakers a year. I have found that most guest speakers are willing to stay all day and repeat themselves!! I usually provide them with water and lunch/snacks. I have found that most guest speakers do not provide notes for students to take, so I ask for their PowerPoint before they come in order to create a student handout. My students are much more engaged when they have something to follow and take notes on. Go for it! Guest speakers enrich the unit and experience! Kimberly

Learning Science Concepts through Play | Posted in Early Childhood

In the last couple of years, I have learned just how important play is to students. Play is just as important in the elementary grades, as it is for students preschool and below. I have learned that allowing students to play through STEM activities, allows them to work out their problem solving skills, monitor their emotions, and enhance their social skills. I believe that as teachers we need to remember that we can't hover. We need to allow our students to have play time. They need this time to enhance their skills in multiple different areas. One of my favorite play activities that students can do is through clay. I have seen so many different students play with clay, but I have never seen the same creation from a different student. This play can be as simple as having clay on the table and letting them create whatever they want, or it can be as complex as asking them to create different structures to hold something or withhold wind or water. I really like the link that you added! I believe that it is so important to allow students to learn and socialize through play as well as different experiments, and these different experiments would be great in the classroom.

The Drake Equation | Posted in Earth and Space Science

The Drake equation is not directly used by scientists in their research. Rather it is often used when talking about life in the universe to non-scientists, such as in astrobiology courses, as James mentioned. One of the keynote addresses I sometimes deliver is on astrobiology, and I discuss the Drake equation quite a lot, as it relates to many fascinating topics regarding the development of life in the universe, where we would expect to find life, and how common we might expect life to be.

The purpose of the Drake equation is not to give a precise answer to that fundamental question -- How many technological civilizations are in our galaxy? -- but to form the basis of discussions by presenting various types of information that we would need to know, if we wanted to answer that question.

So basically the Drake equation is a statement that "stimulates intellectual curiosity about the universe around us, for helping us to understand that life as we know it is the end product of a natural, cosmic evolution, and for helping us realize how much we are a part of that universe." (https://www.seti.org/drakeequation)

What the equation and the search for life has done is focus science on some of the issues concerning life in the universe, specifically the development of life starting with chemical processes, the development of multi-cellular life, and the development of intelligence.
